ROOFING.

Application led June 10, 1926. Serial No. 114,958.

This invention relates to covering or roofing material which may be utilized for. any

uses for particularly 5 known as roll roofing. Roll which it may be adapted but is directed to the typecommonly tofore made usually consists of long sheets or strips of suitable material, such as asphaltroofing.

When these strips are laid on the roof, they are overlapped and nailed to form the joints, butthere tendency the nails ing onv account past the It has also been is always more or less toward warping or raising between with a consequent liability of leakof rain or snow being driven joint through such raised portions. proposed to form interlocking edges but these have been found impractical, as properly it is diiiicult `if not impossible to interlock and fasten long strips of such material. l

In accordance with the present invention, I provide an improved roofing which will overcome the objections to such previous forms 'and which when Alaid will provide a more perfect covering.

The objects of this invention are to provide a new and .improved rooting material which inay be conveniently and cheaply manufactured and which will be particularly eicient and durable in use; to provide roll roofing having a fold or hein-like border or borders formed by folding over the edge or edges; to provide a strip of covering or rooting which ed jacent straight lapping strip;

may be material having one edge folded,

ge is adapted to coact with the ad'- edge of a corresponding overto provide roll roofing which marked or colored to simulate shingles and which when laid will have the appearance of shingling;

and to provide such other advantages and novel features as will be described more fully hereinafter.

In the accompanying drawings illustrating this invention;

Figure l is a plan View showing a strip of roll roofing embodyingI this invention;

Figure terial as Figure 3 is an enlarged taken on taken on Figure 2 is a side view showing the ma- Figure 4: is an enlarged sectional detail the line 4-4 of Figure 2;- and 5 is a plan view showing a modified form of construction, or showing 'onehalf of the strip illustrated in Figure l after the strip In the has been cut in two. form of the invention as shown in roofing as hereor closure between the strips. may be made of any desired width, but I Figur-e 1, the strip or piece 6 represents, any suitable covering or roll rooting material, such as asphalt roofing or the like. The surface of this strip is preferably covered, 00 as shown at 7 withground stone, mineral grits or any of the usual materials adapted for this purpose. Such covering extends approximately across the strip but the uncovered edges or borders are left along 05 either side, as indicated at 8 in Figure 3. These edges or uncovered portions are then folded over and pressed tiUhtl against the face of the strip to form t e olds 9 which extend along the entire length of the roof- 70 ing. This folding and pressing of the edges maybe done in any suitable manner. The surface 7 may be marked as indicated at 10 with any suitable marking or coloring in order to give the appearance of shingles or for the purpose of embellishing or im roving the appearance of the roofing. hen

'the strip or roll has been completed, it is then split along the center, as shown at 11 `to forni two duplicate or similar strips, each 804 upper edge and the straight edge of the next succeeding strip will be placed over this fla so that the roofing nails 12 will pass throug the lower edge of the upper` strip and through the flap and adjacent portion of the lower strip. i

Theproofing may be readily applied in .thil

man ner and when so applied, the flap or fold 9 will prevent or tend to revent water,

` snow, or-the like from .being driven in through the joint formed betweenthe strips. There may be a slight tendenc toward lbuckling' or raising of the lower e ge of the upper strip when the nails are driven, but theflap will also tend to raise or in any event will tend to make a more perfect joint These flaps have found that for ordinary purposes they may be made approximately two inches Wide to effectively serve the pur oses intended. When the strips are provi ed with transilo verse markings 10 to simulate shingles, such markings may be arranged in staggered relation, as shown in Figure 2, and the double thickness shown along the joint further enhances the shingle effect, as it gives the appearance of the thickened butts of shingles.

Instead of making a double Width roll, as

lshown in Figure 1, a single width may be made, as shown in Figure 5, with the flap or fold 9 along one edge only, and the other edge left straight or without such iap.

It is apparent that my improved roofing or covering may be made in various sizes and may be made'of any Suitable material and may be marked or decorated to simulate shingles or in any desired manner, and therefore I do not wish to be limited to the exact form or arrangement herein described, eX- ceptas speciiied in the following claims, in which I claim:

l. A roof covering comprising separate strips laid substantially parallel to the eaves, each strip having its upper edge only folded back upon itself to provide la joint or Hap forming an abutment against the ingress of water thereover, with the lower porlagainst its coated face,

tion of the adjacent strip overlapping said flap and nails through such overlapping portions.

2. A. roof covering comprising strips of felt laid substantially parallel tothe eaves with a water-proofing coating on each strip extending on the outside face to a line adjacent to the upper edge leaving an uncoated portion forming a flap, which flap is folded over ontothe adjacent coated face, the lower edge of the next strip being placed over and coinciding with the lower edge of the flap.

3. A roof covering comprising overlapping strips laid substantially parallel to the eaves, each strip having a' water-proof coating extending from the lower'edge to a line at a distance from the upper edge forming an uncoated l'lap which is turned over and fastening means inserted through the overlapping strip portions and said iiap thereby forming a seal between the overlapping strips.
